Title: Clock pulse generator
Inventor: TSUKADA KAZUMASA
IPC: H03K5/04
Filed: 1981-06-23
Abstract: PURPOSE:To obtain pulses of 50% duty by comparing the amplitude of a sawtooth wave corresponding to the period of an input pulse with a half of the peak value level of the sawtooth wave. CONSTITUTION:The rise of an input pulse Si is differential by a differential reset circuit 1. The differential pulse is applied to a sawtooth wave generating circuit 2 to reset the circuit. Consequently, the period of the sawtooth wave is made to coincide with the that of the input pulse Si. A peak detecting circuit 3 detects the peak level of a sawtooth wave from the circuit 2, reduce the level to a half level Sh and applied the half level to a comparator 4. Since a sawtooth wave is applied to the other input terminal of the comparator 4, an output So is generated as a 50% duty pulse.

Title: Method for filling solid catalyst
Inventor: WATANABE SHIYOUGO
IPC: B01J8/02
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To minimize the incidence of pulverization and degradation of a solid catalyst by first filling the reaction pipe of a fixed bed reactor with dry ice and then filling the pipe with the solid catalyst and removing the dry ice by vaporization, when filling the reaction pipe with the solid catalyst. SOLUTION: First, a reaction pipe is filled with dry ice by dropping it from the top of the pipe and then is filled with a solid catalyst by dropping it likewise. In this case, the filler can be previously packed in a part below the dry ice of the reaction pipe. In addition, the catalyst can be mixed with a dilution substance and the mixture can be packed. Next, the dry ice is removed by vaporization and an additional solid catalyst is packed by dropping it depending on necessity. The amount if filling of the dry ice is preferably to be about 20-60 vol.% of the reaction pipe. The method for removing the dry ice by vaporization after packing the catalyst is not particularly defined with regard to the limitation of the volume to be removed. However, the dry ice can be naturally vaporized after the specified amount if the dry ice is packed and is left alone at abnormal temperature.  Further, it is perfreable to remove the dry ice by vaporizing it with a concurrent action to circulate a gaseous substance containing a small amount of moisture, e.g. an air through the reaction pipe.

Title: Direction control unit for agricultural machine by ultrasonic wave distance detection
Inventor: MIYAJIMA TOSHIO
IPC: G05D1/02
Filed: 1979-07-30
Abstract: PURPOSE: To eliminate the external disturbance due to reflection by object at the back of measured object, by providing the inhibit gate 20 based on the distance limit gate 22.  
     CONSTITUTION: Ultrasonic waves are transmitted from the transmitter 12 fitted to the float 10 toward the direction orthogonal to the progressing direction of the rice- plant implanting machine 1, and the 1st reflection signal reflected from the implanted rice-plant 13 is received at the transmitter 12. Further, since the amplitude of the received signal is smaller than that of the transmitted signal, the signal switching circuit 17 transmits the received signal to the amplifying circuit 19. Since the inhibit gate 20 is used only during the time slightly longer than the time when the ultrasonic wave signal is transmitted and received, the first reflection signal only can pass through the inhibit gate 20 and it is detected at the detection circuit 21 and fed to the time width voltage conversion circuit 23. On the other hand, based on the difference between the time difference between the reference pulse signal and the reception signal, and the set delay time difference from the reference pulse signal of the  measured distance 1 from the output circuit 25, the direction control circuit 26 sets  the direction of progress.
